TAR HEATER.

Application filedfl'uly 12,

1 all whom it may concern: 7

Be it'known that I, HAnoLn J. FRIEDMAN, a citizen of the United States, residing at Savannah, in the county of Chatham and State of Georgia, have invented a new and tar being melted in an open vertical recep tacle, in a kettle or the like, from which the tar is dipped as occasion may require. One object of this invention is to provide a compact device capable of being mounted on a truck, if desired, and from which the tar may be drawn readily without dipping, the structure being peculiarly eflicient so far as saving time in the melting of the tar is concerned.

It is within the province of the disclosure to improve generally and to enhance the, utility of devicesof that type to which the invention appertains.

With the above and other objects in view, which will appear .as the description proceeds, the invention resides in the COHlblI12L- tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in vertical longitudinal section, a device constructed in accordance with the invention, parts remaining in elevation; Figure 2 is a cross section on the line 2-2 of Figure l.

In carrying out the invention, there is provided a base 1 comprising upwardly converging sides 2 connected by ends'3. A'foot 4, preferably consisting of angle members, is secured at 14 to the base 1 and constitutes means whereby the base may be mounted on a support 5 which may be the platform of a vehicle, if it is desired that the device be portable. Any desired number of cross bars 6 are supported on the foot 4 and extend between the sides 2, the cross bars supporting 1922. semi No. 5?4,401.@

a bottom 7, the bottom being secured to the cross bars 6, as shown at 16. The sides 2,

the ends 3 and the bottom 7 may be covered by a lining 8 of asbestos or other refractory material.

Downwardly swinging doors 32 may be I hinged at their lower. edges as shown at 33, to one or both of thesides 2 of the base 1, the doors giving accessto the basel and being held in closed any desired kind.

A horizontally disposed cylindrical tank' 9 is mounted upon the base 1 and is secured thereto as shown at 10. Adjacent to one end, the tank 9 carries, in its upper portion, a sleeve 11 extending downwardly into the tank and upwardly above the tank. A tubular closure 12 fits closely but slidably in the sleeve 11,and is closed at the top, the closure carrying a handle 15, and downward movement of the closure within the sleeve being limited by a stop strip 17 on the 010- That end of the tank 9 which is resure. mote from the sleeve 11 is provided with an outlet 18, in the form of a spout, so located that it will drain the tank completely, thespout being provided with a valve 19. A screen 21 extends between one end of the tank 9 and the bottom of the tank, the screen preferably being made up. of any desired number of inclined bars, the screen being located adjacent to the outlet spout 18.

Air is admitted into the basel to promote combustion, through vent openings in the base. The tar in the tank 9 may be heated through any preferred instrumentality. If it is desired to use liquid fuel in the melting of the tar, burners 22 may be disposed in the base; the burners being in communication with lateral pipes 23 leading to a header 24, valves 25 under the control of an operator being disposed in the pipes 23, the header having a dependingbranch 26 connected by a hose 27 to a valve 28 on a presure tank 29 provided with a pump 30 and with a gauge 31. It is within the scope of theinvention, however, to use any kind of fuel in the device forming the subject matter of this ap plication.

In practical operation, the closure 12 is removed, and the lumps of'tar or like material are introduced into the tank 9 through the sleeve 11, whereupon the closure 12 is again mounted in the sleeve 11. Owing to the fact that the sleeve 11 is of considerable length, and is located as shown and deposition by latches 3450f sary'to dip or ladle the tar, when it is de- 7 scribed, it will be impossible, practically,for moisture to find its Way into the tank 9 along with the tar, and since moisture cannot find its Way into the tank, a dangerous or inconvenient pressure cannot'be generated in the tank. The tar within the tank is melted; by the heat derived'from the burners 22 or their equivalent, and, when the valve 1 9 is opened, the melted tar will flow outwardly through the spout 18. The screen 21 serves to prevent any solid or unmelted lumps of tar from finding their way to the outlet spout l8. 1 i a a The device hereinbefore described affords a simple and convenient; means whereby tar and the like may be melted; it being unnecessired to dipense'the same.

'What is claimed V I In a device of the class described, a boxlike base and a cylindrical tank on the base, thetank being provided at one end with an outlet disposed closeto the bottom of the tank, a sleeve in the top of the tank, a closure insertedinto the sleeveanda screen extended between said end of the tank and the bottom thereof, the screen serving as a guard for the outlet and being'so inclined. asto tend to direct floating lumps toward the sleeve, whereby when lumps of material are introduced by way of the sleeve, such lumps will tend to fall upon floating lumps, thereby reducing the spattering of melted material through thesleeve; the sleeve extending an appreciable distance above and belowthe top 01" the tank for the double purpose' 'oi preventing spattcring through the sleeve-and affording a. large area for frictional contact with the closure.

,In testimony that I claim the foregoing my own, I have hereto ,afiixed my signa. ture in the presence of two witnesses.

HAROLD J. FRIEDMAN.
